Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Example:

[0023] See also Figure 1-5 A crushing material scraping device for a rubber product crusher includes a crushing frame 1, on which two crushing rollers rotating in opposite directions are arranged in parallel on the horizontal axis of the crushing frame 1, and scraping bars 2 that can feed toward the crushing rollers are arranged at the bottom of both sides of the two crushing rollers. The crushing roller includes a crushing roller sleeve 3 with end covers 4 fixedly installed at both ends, and the crushing roller sleeve 3 is circumferentially slidably equipped with multiple crushing wings 8 whose top surfaces can be cocircular with the outer surface of the crushing roller sleeve 3, and also includes an elastic mechanism adapted to the crushing wings 8. In the free state, the top surfaces of the crushing wings 8 remain cocircular with the outer surface of the crushing roller sleeve 3, and also includes an adjustment mechanism for overcoming the elastic mechanism to push the crushing wings 8 out of the outer surface of the crushing roller sleeve 3.

[0024] Specifically, the elastic mechanism includes a spring 9, one end of the crushing wing 8 arranged in the crushing roller sleeve 3 is fixedly installed with a limit plate 6, and the crushing roller sleeve 3 is fixedly installed with a fixed plate 7 at the sliding fit with the crushing wing 8. The spring 9 is sleeved on the crushing wing 8, and the two ends of the spring 9 are respectively fixedly connected to the limit plate 6 and the fixed plate 7. In the free state, the top surface of the crushing wing 8 is cocircular with the outer surface of the crushing roller sleeve 3. When the spring 9 is compressed, the crushing wing 8 can be pushed outward.

[0025] Specifically, the adjustment mechanism includes a central shaft 10 rotatably connected to the middle position of the crushing roller sleeve 3, and a paddle 11 compatible with multiple crushing wings 8 is fixedly installed circumferentially on the central shaft 10. An arc block 12 that is in smooth contact with the paddle 11 is fixedly installed at the bottom of the limit plate 6. The two ends of the central shaft 10 are rotatably connected to the two end covers 4 respectively, and one of the end covers 4 is provided with an adjustment component for adjusting the angle of the central shaft 10. Through the adjustment component, the central shaft 10 can be conveniently driven to rotate in angle, and through the cooperation of the paddle 11 and the arc block 12, the crushing wings 8 can be conveniently driven to rise and fall.

[0026] Specifically, the adjustment component includes a one-way screw 14, and the two end covers 4 are fixedly mounted with end shafts 5 rotatably connected to the crushing frame 1. The one-way screw 14 is threadedly connected to one of the end shafts 5. A sliding rod 15 is fixedly mounted on one side of the one-way screw 14 extending into the interior of the crushing roller sleeve 3, and an adjusting button 16 is fixedly mounted on the other side of the one-way screw 14. A sliding slot 13 that cooperates with the sliding rod 15 for guiding insertion and extraction is provided on the central shaft 10. The adjusting button 16 is used to easily drive the one-way screw 14 to rotate clockwise or counterclockwise, and with the cooperation of the sliding rod 15 and the sliding slot 13, the central shaft 10 is driven to rotate clockwise or counterclockwise by a certain angle.

[0027] Specifically, it also includes a distance adjustment mechanism that drives the two scraping bars 2 to feed toward the middle. The distance adjustment mechanism includes a bidirectional screw 17 that is rotatably connected to the outside of the crushing frame 1. The bidirectional screw 17 is symmetrically threaded with two sliders 19 that slide and cooperate with the crushing frame 1. The two scraping bars 2 are fixedly connected to the two sliders 19 through a guide frame. It also includes an adjusting motor 18 that drives the bidirectional screw 17 to rotate. The adjusting motor 18 is fixedly installed on the crushing frame 1. When the adjusting motor 18 is started, the output shaft of the adjusting motor 18 rotates clockwise or counterclockwise, thereby driving the bidirectional screw 17 to rotate clockwise or counterclockwise, thereby driving the two sliders 19 to move to both sides or to the middle, and then driving the two scraping bars 2 to move to both sides or to the middle, thereby facilitating the spacing adjustment of the two scraping bars 2.

[0028] Specifically, a plurality of crushing guide ribs 20 are fixedly connected to the positions above the two crushing rollers on both sides of the inner side of the crushing frame 1. The crushing guide ribs 20 cooperate with the crushing rollers to facilitate the crushing of rubber products and guide the rubber products so that most of the rubber products fall between the two crushing rollers for crushing.
